Do you measure more than the six basic emotions?

Yes, in addition to the six basic emotions: happiness, surprise, fear, sadness, disgust and confusion – we also calculate measures of engagement and valence, and a general negative emotion classifier.

Engagement: a measure of whether participants have any expressive reaction to a stimulus.

Valence (Net Positivity): a measure of whether a reaction is more positive or negative. This measure helps to elucidate the emotional “tenor” of the viewing experience by deducting Negative from Positive.

Negative (Net Negativity): a measure of whether participants are showing an emotion classified as negative.
